intel/eu: force stride of 2 on NULL register for Byte instructions

The hardware only allows a stride of 1 on a Byte destination for raw
byte MOV instructions. This is required even when the destination
is the NULL register.

Rather than making sure that we emit a proper NULL:B destination
every time we need one, just fix it at emission time.
